The contribution of 211 particles to the mechanical reinforcement mechanism of 123 superconducting single domains
J. -P. Mathieu, I. G. Cano, T. Koutzarova +5
Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tes…
